A kind of aquaculture water quality improver and preparation method thereof

Abstract

The invention discloses a water-quality improver for aquaculture. The water-quality improver comprises the following components in parts by weight: 5-10 parts of rape, 5-10 parts of corn, 7-15 parts of spinach, 2-5 parts of bacillus, 3-7 parts of photosynthetic bacteria, 2-5 parts of nitrobacteria, 5-10 parts of amino acid and 2-10 parts of chitosan. The invention also discloses a preparation method of the water-quality improver for aquaculture. The preparation method is simple and low in cost. By the water-quality improver for aquaculture, organic matters in aqueous bottom mud for aquaculture can be decreased, the aerobic layer is thickened, the growth and reproduction of aerobic microorganism and the decomposition of organic pollutants are accelerated, and micro-nutrients required for normal growth of aquatic products can also be provided so that the quality of the aquatic products is improved.

Description

Technical field: [0001] The invention relates to the field of aquaculture, in particular to an aquaculture water quality improver. Background technique: [0002] Aquaculture is an important part of my country's national economy. Mariculture, as a pillar industry of aquaculture, has made important contributions to the construction of the national economy and the improvement of people's living standards. However, with the rapid development of the marine aquaculture industry, problems such as sea area pollution, aging shrimp ponds, black and odorous bottom sediment, and the outbreak and prevalence of large-scale catastrophic viral diseases have been quickly exposed, making people question the traditional predatory farming model. [0003] The traditional breeding mode, especially the high-density farming mode, mostly consumes a large amount of high-protein feed and maintains the production mode at the cost of polluting the pond itself and the nearshore environment. In addition, ...

Problems solved by technology

However, with the rapid development of the mariculture industry, problems such as sea area pollution, aging shrimp ponds, black and smelly bottom mud deposition, and the outbreak and prevalence of large-scale catastrophic viral diseases have been quickly exposed, making people question the traditional predatory farming model.

[0003] The traditional breeding mode, especially the high-density farming mode, mostly consumes a large amount of high-protein feed and maintains the production mode at the cost of polluting the pond itself and the nearshore environment. In addition, farmers use a large amount of disinfectants, Shrimp medicines such as antibiotics, and even human medicines for fish (shrimp) use higher and higher doses of medicines, and the toxicity of the medicines is getting stronger and stronger. , the vicious circle of getting sicker and sicker

In aging ponds, toxic chemicals such as breeding residues, feces, dead animals and plants, and disinfectants and antibiotics have been deposited on the bottom of the pond for many years, forming black sludge. The sludge is rich in organic matter, and anaerobic microorganisms dominate. The increase accelerates the anaerobic decomposition of organic matter, consumes a large amount of oxygen in water, and produces NH 3 、H 2 S. NO 2 and other toxic substances, affecting the normal growth and development of prawns, and the black sludge contains a large number of eggs of pathogenic bacteria, parasites and harmful organisms, which increases the transmission route of the source of disease in the pond, and makes the amount of fish (shrimp) medicine used in the production process increase, the quality of aquatic products decreased
